What happened?

The zonal average plot for the MPAS+JEDI pythia cookbook currently crashes with ValueError (and subsequent cell's plot also does not display): https://projectpythia.org/mpas-jedi-cookbook/notebooks/mpas-advanced/#zonal-average

The error looks like:

---------------------------------------------------------------------------

What did you expect to happen?

I expected a nice plot, not a crash.

Can you provide a MCVE to repoduce the bug?
